[0036] The upper rack 5 is provided with a pressing plate 9 inside, and the end plate 13 is fixedly arranged at the bottom end of the pressing plate 9.

[0037] The lower rack 1 is provided with a transmission assembly 2 on one side, and the transmission assembly 2 is provided with a rocker arm 3.

[0038] The elastic downward pressing assembly 6 drives the pressing plate 9 to press down, so that the upper extrusion roller 8 is tightly pressed on the top of the corresponding lower extrusion roller 7, and the rotation of the rocker arm 3 can drive all the lower extrusion rollers 7 to rotate synchronously through the transmission assembly 2. After the rotation of the lower extrusion rollers 7, the corresponding upper extrusion roller 8 will also start to rotate under the action of friction. At this time, the deformed and raised bearing pad is placed between the lower extrusion roller 7 and the upper extrusion roller 8 at the front, and with the rotation of the two, the bearing pad will be moved from front to back and clamped between the lower extrusion roller 7 and the upper extrusion roller 8. With the rear movement of the bearing pad, the bearing pad will be pressed by each pair of contacting lower extrusion rollers 7 and upper extrusion rollers 8 one by one, and finally it will be guided out from the rear side of the correcting device. Through multiple extrusions, the deformed and raised bearing pad is flattened, the parallelism is corrected, and the qualified rate in the subsequent detection process is increased.

[0039] The bearing pad needs to be pressed flat enough, such as Figure 4 、 5 , as shown in the lower part of the figure, the upper rack 5 is fixedly provided with a plurality of sleeves 12 at the top, and the pressing plate 9 is fixedly provided with a plurality of guide rods 11 at the top. The guide rod 11 and the sleeve 12 correspond one by one, the top of the guide rod 11 extends to the top of the upper rack 5 through the sleeve 12, and the guide rod 11 can move vertically up and down along the sleeve 12. The elastic downward pressing assembly 6 comprises a top frame 601, and the top of the guide rod 11 is fixedly connected with the top frame 601.

[0040] The upper rack 5 is fixedly provided with a threaded column 605 at the top, and the threaded column 605 is provided with an adjusting sleeve 604 at the top through a threaded sleeve. The height of the adjusting sleeve 604 can be adjusted by rotating it, and the top of the adjusting sleeve 604 is rotatably connected with a mounting piece 603. The top of the mounting piece 603 is fixedly provided with a spring 602, and the top of the spring 602 is fixedly connected with the top frame 601.

[0041] The spring 602 located above the upper rack 5 is always in a stretched state, and the stretched spring 602 pulls the top frame 601 downward by its own elastic force. The top frame 601 is thus pushed vertically downward by the guide rod 11, and the pressing plate 9 is thus pulled downward by the guide rod 11, so that the upper extrusion roller 8 is pressed downward by the lower extrusion roller 7, and thus the bearing pad is pressed downward during the correction work. During the correction work, the adjusting sleeve 604 can be rotated, and the rotation of the adjusting sleeve 604 makes it move up and down along the threaded column 605 under the action of the thread. The mounting piece 603 moves synchronously with the adjusting sleeve 604 and drives the spring 602, controls the length of the stretching, and adjusts the size of the elastic force, so as to control the extrusion force during the correction process.

[0042] In order to make all the lower extrusion rollers 7 move synchronously, as Figure 1 、 6The transmission assembly 2 includes a transmission box 201 fixed on one side of the lower rack 1, one side of the transmission box 201 is provided with a cover plate 202 through bolts, the cover plate 202 is rotatably connected with a driving shaft 207, the rocker arm 3 is fixed on one end of the driving shaft 207, the other end of the driving shaft 207 extends into the transmission box 201 and is fixed with a driving bevel gear 208.

[0043] The inner wall of the transmission box 201 is rotatably connected with a transmission shaft 203, the outer end of the transmission shaft 203 is fixed with a plurality of transmission bevel gears 204, the driving bevel gear 208 is engaged with one of the transmission bevel gears 204, so that the rotation of the driving bevel gear 208 can drive the transmission bevel gears 204;

[0045] The driving lower extrusion roller 7 rotates to correct the bearing pad, first, the rocker arm 3 needs to be manually driven to rotate, the rocker arm 3 drives the driving shaft 207 and the driving bevel gear 208 fixed on one end of the driving shaft 207 to rotate, the driving bevel gear 208 is engaged with one of the transmission bevel gears 204, so that the transmission bevel gear 204 is driven to rotate, which makes the transmission shaft 203 and all the transmission bevel gears 204 on the outer end of the transmission shaft 203 start to rotate, the transmission bevel gear 204 drives the driven bevel gear 206 engaged therewith to rotate, the driven bevel gear 206 is connected to the lower extrusion roller 7, and rotating the rocker arm 3 can drive all the lower extrusion rollers 7 to rotate synchronously.

[0046] In the correction process, in order to avoid the transverse deviation of the bearing pad, as shown in Figure 6 The lower extrusion roller 7 is provided with annular side plates at both ends, the diameter of the annular side plate is greater than the diameter of the lower extrusion roller 7, the contact part of the lower extrusion roller 7 and the upper extrusion roller 8 is located between the two annular side plates, the inner wall of the lower rack 1 is provided with two detachable supporting plates 4, the top end of the supporting plate 4 is flush with the top end of the lower extrusion roller 7, and the lower extrusion roller 7 is located between the two supporting plates 4.

[0047] Before the correction, the bearing pad is placed on the top of the front side of the bracket 4, and the bearing pad is pushed along the top of the bracket 4 to move into the lower rack 1. When the bearing pad contacts the lower extrusion roller 7, it is extruded by the rotation of the lower extrusion roller 7. After extrusion, the corrected pad finally reaches the top of the rear bracket 4 and moves backward under the drive of the lower extrusion roller 7. During the correction process, since the diameter of the annular side plate is greater than the diameter of the lower extrusion roller 7, the bearing pad can be prevented from being offset laterally to affect the correction.

[0048] Only the bearing pad with qualified parallelism after correction can smoothly pass through the limiting assembly 10, such as Figure 2 、 3 , 4, 9, the top of the rear bracket 4 is provided with a limiting assembly 10, the limiting assembly 10 includes a fixed shaft 1002 rotatably connected to the inner wall of the upper rack 5, the outer end of the fixed shaft 1002 is fixedly provided with a baffle 1001, one end of the fixed shaft 1002 is provided with a positioning cylinder 1003, the positioning cylinder 1003 is fixedly provided on the inner wall of the upper rack 5, the outer end of the positioning cylinder 1003 is provided with a fastening bolt through threads, and the fixed shaft 1002 can be fixed after the fastening bolt is tightened.

[0049] The other end of the fixed shaft 1002 extends to the outside of the upper rack 5 and is fixedly provided with a handle 1004, the handle 1004 is fixedly provided with an indicating protrusion, and the outside of the handle 1004 is provided with a scale ring 1005 fixed on the upper rack 5.

[0050] The bearing pad after extrusion correction moves backward under the drive of the lower extrusion roller 7 and reaches the top of the rear bracket 4. The bearing pad moves backward along the rear bracket 4 and passes through the limiting assembly 10. At this time, the baffle 1001 is in the inclined device, and there is a gap between the rear end of the baffle 1001 and the top of the rear bracket 4. The height of the gap is slightly greater than the thickness of the normal bearing pad. Therefore, if the bearing pad has been sufficiently corrected, it can smoothly pass through the gap and continue to move backward and finally separate from the last lower extrusion roller 7 to complete the correction. If the bearing pad is not sufficiently corrected, it means that the bearing pad still has a deformation, and the bearing pad cannot pass through the gap, and the bearing pad blocked by the baffle 1001 cannot continue to move backward.

[0051] At this time, the rocker arm 3 can be reversely rotated, so that the lower extrusion roller 7 and the upper extrusion roller 8 are reversely rotated, the bearing pad originally moved backward is driven to return to the inside of the lower rack 1, and the extrusion correction work is performed again until the bearing pad can smoothly pass through the gap, so as to ensure that the corrected bearing pad can be qualified, and the effect of the correction device is better.

[0052] By rotating the handle 1004, the fixed shaft 1002 can be driven to rotate, and the inclination angle of the baffle 1001 is adjusted according to the scale on the scale ring 1005.

[0053] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
